ATTORNEY 5 United States Patent O APPARATUS FOR THE TREATMENT OF PRODUCTS OF FIBROUS MATERIAL Walter Marty, Uzwil, Switzerland, assignor to Maschinenfabrik Benninger A.-G., Uzwil, Switzerland Application January 18, 1954, Serial No. 404,569

Claims priority, application Switzerland January 21, 1953 1 Claim. (Cl. 68-43) The present invention relates to an apparatus for treating products of fibrous material, which are to be guided through a treating medium.

Various types of apparatus are known for the treatment of fibrous material products by a medium such as a fluid or the like, and more particularly for the treatment of spreadingly guided fabric webs or the like (e.g. in so-called broad washing machines) as well as of fibrous material yarns in form of warps or skeins (e.g. in warp dressing machines or in skein dyeing apparatus) etc., whereby particular mechanical auxiliary means are provided to obtain goods which have been treated as uniformly as possible. However, in practice the known kinds of apparatus for treating or conditioning are insuflicient for one reason or another.

In contradistinction to known constructions, the apparatus according to the present invention for treating fibrous material products to be passed through a treating medium is characterized in that at least one operating body is provided in the zone of the treating medium, which body in addition to a drive for continuously swinging the operating body to and fro about an axis is provided with operative parts extending in direction of the axis thereof, which are designed either to immediately influence the treating medium and thereby indirectly influence the product of fibrous material to be moved transversely to the operating body, or to swing the fibrous material product to and fro and thus also influence the treating medium accordingly.

This permits handling the treating operation so as to obtain a high degree of uniformity with respect to the quality of the fibrous material product leaving the treating medium.

Other treating media which may be used besides liquid, are for example: vapour, air or other gases and as well mixtures such as are used e.g. for steaming, drying, condensing, fixing etc. of textiles.

Other objects and advantages of the invention will become apparent from the description now to follow the preferred embodiment thereof, in which reference will be had to the accompanying drawing, in which:

Fig. 1 is a view, partially in axial section, of an apparatus according to the invention,

Fig. 2 is a sectional view along line 2-2 of Fig. l; and

Fig. 3 is a sectional view along line 3-3 of Fig. 1.

Solely for sake of simplicity, only one treating fluid and one fibre material web are discussed in the embodiment hereinafter described, whereby, with respect to the practical application of the idea of the invention, this places no restriction whatsoever on the scope of protection either, with respect to the kind of the treating medium or with respect to the fibrous material.

The apparatus according to the invention comprises an operating body 1 consisting of a tube which at both ends is supported in pedestal bearings 4 and 5 by means of inserted coaxial stub shafts 2 and 3. The stub shafts 2 and 3 traverse apertures which are provided in two 2,918,813 Patented Dec. 29, 1959 ICC 3 as well as on the tank 6 by means of rings 8 and 9.

The collars 7 prevent the fluid from flowing out of the tank 6 in the region of said stub shafts 2 and 3. Two set collars 10 and 11,'which are mounted on the stub shaft 3 and abut the bearing 5, secure the operating body 1 against axial displacement. A fork 12 is fastened by a clamping screw 13 at the free end of the stub shaft 3. Reference numeral 14 designates a pedestal bearing traversed by a shaft 15 carrying on one end the pulley 16 of a pulley drive and provided on the other end with an eccentric pin 15a. The latter is in engagement with a slide ring 17, positioned between the legs of the fork 12 and which, when the shaft 15 is driven, sets the fork 12 in an oscillating motion, which is transmitted to the operating body 1 by the stub shaft 3; the axis of the stub shafts 2 and 3 represents the axis of oscillation. The angular value of said oscillatory movement designated by a in Fig. 3 is determined by the eccentricity of the pin 15a on the drive shaft 15 as well as from the distance of the latter from the axis of oscillation, and the frequency of oscillation is determined by the speed of the drive shaft 15.

The operating body 1, as seen in Figs. 1 and 2, has four longitudinal flanges 19 provided around the circumference of the tube, the fibre material web A travelling over two deflecting rolls and 96 being guided substantially parallel to said flanges. As is evident, during oscillation of the operating body 1 said longitudinal flanges 19 are rocked alternately and in pairs in a direction towards and away from the fibre material web A, being permitted to contact the fibre material web A or not, depending on the selected conditions.

When using an operating body of the described type, it is also possible to simultaneously treat two fibre material webs, one being fed in the zone of the lower pair of flanges 19 and the other in the zone of the upper pair of flanges 19 of the operating body 1 and parallel thereto, the deflecting rolls 95 and 96, of course, not being required in this case.

It is thought that the invention and its advantages will be understood from the foregoing description and it is apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing its material advantages, the form hereinbefore described and illustrated in the drawings being merely a preferred embodiment thereof.

What I claim is:

An apparatus for treating a web of fibrous material with a treating medium, comprising, in combination, at least one hollow elongated body immersible in the treating medium, four projecting agitating parts on said body equally spaced around the outside periphery of said body and each having a substantially flat flange thereon, the flanges on two adjacent projecting part-s being substantially parallel to each other, and the flanges on the other two projecting parts projecting in the opposite direction from the flanges on the first two projecting parts and being substantially parallel to each other, each of said agitating portions extending longitudinally of said body, means for oscillating said body about a longitudinal axis thereof through only a small part of a revolution and at a high frequency, and means for guiding the web of fibrous material through said apparatus in two parallel flat planes, one plane close to and substantially parallel to the flanges on said two adjacent parts and the other plane close to substantially parallel to the flanges on 3 said other two projecting parts, whereby the treating medium will be agitated and the Web of fibrous material will be oscillated in a direction transverse to the plane thereof.
